MERRITT GALLY, OF BROOKLYN, NEW YORK.

PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 707,770, dated August 26, 1902.

Application filed April 16, 1902. Serial No. 103,082- (No model.)

To all whom, it may concern:

Be it known that I, MERRITT GALLY, of Brooklyn, county of Kings, and State of New York, have invented new and useful Improvements in Printing-Presses, of which the following is a specification.

My invention relates to the form-inking apparatus of printing-presses; and it consists, chiefly, in a tripping device which prevents one or more of the form-rollers from inking the form while passing over it in one direction, but causes it to ink the form while pass ing in the opposite direction. Devices for this purpose 1 do not claim, broadly, to be new, as I have used mechanism for this purpose on an upright bed-and-plate press for more than fifteen years.

In this present application I show and describe a very much improved and more durable device, which is also more reliable and certain in its action.

In the figures of the drawings, Figure 1 is a side view of one of the upper parts of the roller-carriage Ways attached to a portion of the framework of a press, showing in movable connection therewith one of the ends of the roller-carriage frame, having therein its rollers, journal-boxes, and the roller-trip. Fig. 2 shows the roller-carriage same as in Fig. 1, except that its position is at the lower end of the carriage-way, the roller having been tripped for its upward inking of the form. Fig. 2 is a front edge view of one of the journal-boxes, showing its added extension and stop-catch. Fig. 3 is a side and sectional view of the adjustable spring-tension device, and Fig. 4 is a front View of the entire mechanism.

In Fig. 1, F F represent the upper part of one of the roller-carriage ways, there being two, one for each side of the press. The carriage-WayF F is attached to the frame of the press, the part of the frame being shown broken away at A A.

B B represent the body part of one end of the roller-carriage, the other end being simplya reversed duplicate of the one shown and on the opposite side of the press, the two ends being tied together by means of rods jj, the two ends, with the tie-rods, forming the complete carriage.

C C 0 represent the end bearer-wheels or trucks of the form-rollers, their journal showing ate c 0 resting in the journal-boxes a a, C0 The trucks C and 0 travel on the bearer W of the carriage-way. The truck 0 is suiiiciently out of line with the trucks 0 and O, as shown in Fig. 4, to travel on a part of the face of the bearer, which has projecting from it the lifting-cam K. The journalbox 0. has an extension 0. projecting downward from its lower end and has in it a stopcatch h. This projection and pin are shown in transverse view in Fig. 2. The cut-away portion of the journal-box at a;, Fig. 1, is to allow the entry of one of the fingers of the hand for drawing out the box for inserting the roller-journal, and the purpose of the extension at the lower end of the journal-box is to avoid covering the finger-way with the body of the latch-lever G H. A latch-lever G, having a projecting latch i, is pivoted at g, the latch when operated articulating with thelatch-pin 7L. ning on the bearer W remain on the face of the bearer constantly, and when moving downward continue to their position below the form, as shown in Fig. 2, and return in like contact with the bearer. The roller truck 0 when reaching the cammed face of the bearer above the form is forced away sufficiently for the catch-pin h to be caught by the latch 5, and during the remainder of its movement downward the truck stands free from the bearer. When the roller-carriage is turning the angle of the carriage-way at the top of the press, the line of the position of the carriage is a cord of the curve of the angle and the angle of the wayis sufficiently raised to act as a cam for lifting the roller to latching position. When not high enough or the carriage-way is entirely on a straight line, the cam K is necessary on a part of the carriage-way, as shown, to lift the roller. Attached to or forming a part of the latchlever is a projecting arm H, which carries a trip-pin 0. When the roller-carriage reaches its position, (shown in Fig. 2,) the pin 0 strikes the tripping-stop S and relieves the latch, allowing the truck 0 to take its place on the face of bearer for its return movement. The

angle-piece H of the latch-lever is removed sufficiently away from the latch i to allow the journal-box to be drawn out far enough to re The form-roller O and 0 run-- move theform-roller and projects far enough from the line of the lever to reach the stop S on the frame of the press. 13' B of Fig. 2 represent the bearer at the side of the typeform of the press, a front view of which is shown in Fig. 4, and the described movement of the roller-trucks shows that the rollers O and C ink the form while going down and returning, while the roller is held free from the form while going down and only inks the form on its return upward movement, thus beginning at the lower edge of the form to apply its fresh and full amount of ink. The operating tension of the latch is applied by means of the bar D, which is pivoted to the latch-lever at n and has a movement up and down, guided byastud (Z in the slot 61'. The

bar D is turned at its upper end to a right angle, as shown in Fig. 3, and is forced down- Ward by the stop E against the tension of springfin socket e to relieve the latch, which has again caught the latch-pin near the end of the upward movement of the carriage while the truck 0 was returning over cam K. This is to allow the roller to fall backward to its normal position for receiving its ink from the distributing-cylinders of the press. The rods and springs for holding the form trucks against the bearers are marked in the drawings b b 12 The tension of springf, Fig. 3, is adjusted by means of a set-screw Z, having thereon a follower e. The connecting-bar e, pivoted at 'm to the roller-carriage, is for connecting the carriage with the machinery of the press.

The tripping device, as described, may be used in connection with either one or more of the form-rolls, as desired.

I claim 1. In the form-roller carriage of a printingpress, a roller journal-box; having a catchpin forming a part thereof, and projecting from its side; a lever-latch crossing the side face of the box to articulate with the catchpin; one arm of the lever-latch extending beyond the front of the journal-box to articulate with a tripping-stop.

2. In the form-roller carriage of a printingpress a roller journal-box; adepression in the box, forming a finger-socket for moving the box by hand; a tripping device formed of a lever-latch and catch-pin; and an extension of the journal-box reaching below the box proper as a base for the catch-pin, to prevent the lever-latch from obstructing the fingersocket.

3. In a form-roller trip; a journal-box with latch-pin; a lever-latch, and an operating-bar movably attached thereto; the bar provided with a spring-tension device, and an opposing stop; the spring device for securing connection of the latch with its latch-pin, and the opposing stop for releasing the latch from the pm.

4. In a form-roller-tripping device for printing-presses; the combination with the roller journal-box and lever-latch; of the holdingcatch; and the operating-bar with spring, connected to the lever-latch, to keep the latch in engagement withits holding-catch during the time the roller is prevented from inking the form.

5. In a form-roller-tripping device for printing-presses the combination-of the roller j on rnal-box; the lever-latch; the operating-bar movably attached to the lever-latch; the tripping-stop for giving motion to the operating-bar in one direction; and the spring for producing the return movement of the bar.

6. In aformroller-tripping device for printing-presses; the combination with the leverlatch, of the operating-bar; the socket-spring,

the follower, and means for adjusting the tension of the spring.
